Cogged Belt

Designed to support reliable field operation and planned overhauls, the Cogged Belt (OEM 550 762 38) provides an aftermarket solution for the rock drilling machine assembly. It transfers or supports rotational and mechanical load within the drive train, helping maintain synchronized movement between connected components.

This aftermarket option is intended to support planned maintenance and faster parts sourcing while preserving the required application fit. Application data associates this reference with DD321-40 and DD420-40; configuration and serial-number checks are recommended before purchase. Accurate mating dimensions support stable engagement and help reduce unwanted play, edge loading or vibration in the rotating assembly.
